Google has launched Gmail for Mobile 2.0, an application for mobile devices that allows users to continue working on their email even with low or no cellular signal at all.

The application supports some basic offline access on phones like the Nokia N95, Sony Ericsson W910i, and BlackBerry Curve. It also allows access multiple Gmail or Google Apps email accounts from the same application.

The company says the entire client was rearchitected to push all the processing to the background, greatly improve the client-side caching scheme and optimize every bottleneck piece of code they could find.

Users can expect an overall performance improvement, new powerful shortcut keys and support for 35 languages.

Users can visit m.google.com/mail from their mobile browser to download the new Gmail for mobile for your phone.
